</script>
Use
import {push, splice} from 'micromark-util-chunked'
// …
nextEvents = push(nextEvents, [
['enter', events[open][1], context],

splice(events, open - 1, index - open + 3, nextEvents)
// …
API
This module exports the following identifiers: push, splice. There is no default export.
push(list, items)
Append items (an array) at the end of list (another array). When list was empty, returns items instead.
This prevents a potentially expensive operation when list is empty, and adds items in batches to prevent V8 from hanging.
Parameters
list(Array<unknown>) — List to operate onitems(Array<unknown>) — Items to add tolist
Returns
list or items
splice(list, start, remove, items)
Like Array#splice, but smarter for giant arrays.
Array#splice takes all items to be inserted as individual argument which causes a stack overflow in V8 when trying to insert 100k items for instance.
Otherwise, this does not return the removed items, and takes items as an array instead of rest parameters.
Parameters
list(Array<unknown>) — List to operate onstart(number) — Index to remove/insert at (can be negative)remove(number) — Number of items to removeitems(Array<unknown>) — Items to inject intolist
Returns
void
